Hi Linus,
First up, this tree contains a backmerge of your tree, as it merges cleanly
but then fails to build on ARM due to an API change, I've included the
fixed up patch in the merge commit.
The unmerged, unfixed tree is in my drm-next branch if you want to confirm
things. The fixup is 3 trivial ^regulator_set_optimum_mode^regulator_set_load
in drivers/gpu/drm/msm/dsi/dsi_host.c.
I've also been delayed waiting for Grant's tree to merge, but that is in
now so I'm not dragging in stuff from that any longer.
Highlights:
Core:
Virtual GEM layer merged, this has been around for a long time,
and it provides a software backed device that allows userspace to
use it as a GEM shared memory handler. This makes it a lot easier
to do certain things when you have no GPU but still have to deal with
DRI expectations.
atomic helper updates.
framebuffer modifier interface added.
i2c over auxch displayport fixes.
fb width/height confusion fixes.
new driver for ps8622/ps8625 bridge chips
lots of new panels
i915:
more plane atomic conversion
vGPU guest support for XenGT
Skylake workarounds and fixes
Y-tiling support
work on dynamic pagetable allocation
EU count report param for gen9+
CHV fixes (no longer prelim)
remove ilk rc6
frontbuffer tracking for fbc

output csc support
new queries for userspace debug support
new VCE packet
nouveau:

gm107 graphics support
more gm20x bringup (waiting on signed nvidia fw).
amdkfd:
multiple kgd instance support

msm:
stolen memory support
DSI and dual-DSI support
snapdragon 410 support
exynos:

Hmm. The odd Intel PCI resource mess is back.
Or maybe it never went away.
I get these when suspending. Things *work*, but it's really spamming
my logs a fair bit:
i915 0000:00:02.0: BAR 6: [??? 0x00000000 flags 0x2] has bogus alignment
pci_bus 0000:01: Allocating resources

i915 0000:00:02.0: BAR 6: [??? 0x00000000 flags 0x2] has bogus alignment
That resource is complete garbage. "flags 0x2" is not even a valid
flag value. I'm *guessing* it might be IORESOURCE_ROM_SHADOW, but if
that is valid, then it should also have have had the IORESOURCE_MEM
bit, and it doesn't.
(The low 8 bits of the resource flags depend on the high bits, which
is why I say that I'm "guessing" at that ROM_SHADOW bit. It could be
something else, like a IORESOURCE_MEM_CACHEABLE PnP bit - but that
should not show up for PCI, and "BAR 6" is normally the ROM resource,
so the ROM_SHADOW bit makes some sense.
The only place that sets IORESOURCE_ROM_SHADOW that I find is the x86
pci_fixup_video() function. That one checks for PCI_COMMAND_IO |
PCI_COMMAND_MEMORY in the PCI command word, though. Why are the other
bits not set?
Both i915/dri people and PCI people on the Cc. This warning does *not*
happen at bootup, but only at suspend time. So my suspicion is that
somebody messes with the PCI ROM resource, and disables it or
something, but the IORESOURCE_ROM_SHADOW never gets cleared. And then
because res->flags is non-zero, the PCI scanning code doesn't ignore
the resource.
Just before the whole bogus alignment check, the PCI code does
if (!(r->flags) || r->parent)
continue;
(don't ask me about the odd parenthesis) which *should* have
triggered, but that IORESOURCE_ROM_SHADOW bit screws things up.
Anybody?

I'll look into this. It's been around a long time, but hasn't
percolated to the top of my list until now.
https://bugzilla.kernel.org/show_bug.cgi?id=16063 says "echo 1
>/sys/bus/pci/rescan" is also a reproducer.

Your i915 does not have a ROM BAR in hardware. If the default video
device has no ROM BAR, pci_fixup_video() sets IORESOURCE_ROM_SHADOW
even though the resource flags are zero because the BAR itself doesn't
exist.
If IORESOURCE_ROM_SHADOW is set, pci_map_rom() assumes there's a
shadow ROM image at 0xC0000. Is there a shadow image even if the
device itself doesn't have a ROM BAR?
We could fabricate a resource even if the BAR doesn't exist, e.g.,
"flags = IORESOURCE_MEM | ... | IORESOURCE_ROM_SHADOW", but that
would be ugly and error-prone in other places that use the ROM.
Matthew added dev->rom for ROM images supplied by the platform
(84c1b80e3263 ("PCI: Add support for non-BAR ROMs")). A shadow
image seems like a similar thing. I think it would be cleaner to get
rid of IORESOURCE_ROM_SHADOW altogether and instead set "dev->rom =
0xC0000" if there's a shadow image, e.g.:
int pcibios_add_device(struct pci_dev *dev)
{
if (dev-is-default-vga-device) {
dev->rom = 0xC0000;
dev->romlen = 0x20000;
}
pa_data = boot_params.hdr.setup_data;
while (pa_data) {
...
if (data->type == SETUP_PCI) {
rom = (struct pci_setup_rom *)data;
if (dev-is-rom-dev) {
dev->rom = ...
dev->romlen = rom->pcilen;
}
}
}
But the rules for figuring out which image to use seem ...
complicated.

On UEFI systems, there's no special reason to believe that there's
anything at 0xc0000 - it depends on whether a CSM got loaded or not.
Everything is awful. So...

I don't know what we want to do here. This is, at some level,
fundamentally wrong - however, it also wouldn't surprise me if this is
also the only copy of the video ROM we have on some UEFI systems,
especially since I believe that Windows 7 still required that there be
a legacy ROM it could use for bootloader modesetting on UEFI
platforms. So simply making this conditional on BIOS may break
existing machines. But if there *is* a ROM there then we should be
able to id it from the usual video ROM signature?

I'm not sure why we want that IORESOURCE_ROM_SHADOW thing at all, but
yes, if what this is all about is the magic video ROM at 0xc0000, then
(a) it should have nothing what-so-ever to do with the actual PCI
BAR, since it's been *ages* since people actually had an expansion rom
like that, and it's much more common that the video ROM comes as part
of the system BIOS on laptops etc.
(b) yes, the sane thing to do would be to just look for the ROM
signature, 0x55 0xaa at 2kB incrementing headers (and checking the
proper checksum too).
There is no way to see that from the PCI device state, because as
mentioned, quite often the "ROM" is entirely fake, and is not just
some shadowed copy of a real underlying hardware ROM, but is
fundamentally just a RAM image decompressed from some other source and
then marked read-only.

It's used in the PCI layer to say "Read from 0xc0000 rather than the
ROM BAR" and then ends up as a shorthand for "Was this the boot video
device" in various places because we're bad at software.

If only - nvidias used to rewrite their image at runtime.

Very likely yes. With integrated APUs and mobile dGPUs, the vbios
image is often stored as part of the system rom rather than as a
dedicated rom for the GPU. The vbios image is then copied to the
shadow location during sbios init to provide OS access to the rom.

This commit introduces a regression relative to v4.0 on an Intel
D945GCLF2 mainboard[1] (Atom 330) with Intel 82945G/GZ onboard graphics

drm/i915: Allocate connector state together with the connectors
Connector states were being allocated in intel_setup_outputs() in loop
over all connectors. That meant hot-added connectors would have a NULL
state. Since the change to use a struct drm_atomic_state for the legacy
modeset, connector states are necessary for the i915 driver to function
properly, so that would lead to oopses.

Reverting just this commit on top of yesterday evening's
v4.1-rc6-52-gff25ea8 avoids the problem for me.
Using the very same kernel, other i915 based systems are fine for me:

Hmm. Smells like a connector with a NULL state pointer, and the bad
commit touched exactly the part that sets it up. I can't immediately
spot any place where we'd forget to set it up though.
Can you try with something like this so we'd at least find out which
connector(s) is/are at fault here?

With the patch applied, the kernel (v4.1-rc6-104-g4b17069) locks up even
harder, so I had to switch to a serial console in order to fetch the
boot messages:
[ 13.492784] connector = ffff880079bb8000
[ 13.910439] connector = ffff8800795b5800
[ 14.463114] connector = ffff8800795b6000
[ 14.700707] connector = ffff8800795b6800
[ 14.869418] connector = ffff8800795b7000
[ 14.923848] connector = ffff8800795b7000
Full, gzipped, bootlog attached - thanks a lot for your efforts.
